new and useful lmprovements in Ties or Any cher-Mates, of which the following is a specilication.

This invention relates to a tiel or anchor plate designed to be used between two timbers where one timber has a cross-bearing on the one below' to rigidly fix said timbers in relative positionl n The object of the invention is to provide a simple, eliicient, and inexpensive device of this character having means to securely engage the timbers and hold them against relative movement.

In the accompanying drawings, Figure 1 isv a plan view of one side of the anchor-plate.

Fig. 2 is a similar view of the reverse side tFhereof. Fig. 3 is a section on the line 3 3 of As shown, the device comprises a metallic plate 1, preferably rectangular in form and provided with a central opening 2 for the passage of a bolt or spike to fasten the timbers together. r

I- The plate is adapted tolie between the two timbers and is provided upon its opposite sides with spurs or sharpened ribs adapted to be embedded in the timbers to firmly hold the same against movement. What may be termed the upper side of the plate is provided with a pair of longitudinal spurs or ribs 3, arranged at and parallel with two of the side edges thereof, and between these spurs are other' sets or pairs of spurs 4 and 5, extending in parallel relation to each other and to the spurs 3, the two sets of spurs 4 and 5 extending from the opposite sideedges of the plate on oppositeisides of the center line thereof and terminating at their inner ends outside of the central opening 2, thus allowing the portion of the timber resting against the center of the plate to come close down to the openings to secure an effective connection. The spurs or ribs 3,A fl, and 5 are sharpened or tapered to cutting edges, adapting them to sink or become embedded in the timber, so that the latter will be fixed to the ancher-plates. The reverse side or under side of the plate 'is provided with similar sets or pairs of ribs or spurs 3', 4', and 5', such spurs being, however, arranged at right angles to the spurs on the upper side. The spurs upon one 'side are adapted to engage the upper timber and those upon the reverse side the lower timber, the relative right angu ar arrangement of the two sets of spurs adapting them to effectively engage the crossing timbers.

The plate may lirst be placed upon the lower timber and struck by means of a hammer or other tool to force the underlying set of spurs therein, after which the upper timber is placed in position and forced downward in any suitable manner, so as to be engaged by the upper set of spurs. Upon then passing the bolt through the connected parts the two timbers and plate will be firmly fastened in relative position, as will be readily understood. Any other suitable means of joining the parts may, however, be employed.

It will 'be seen that the invention provides a simple form of tie or anchor plate which may be inexpensively manufactured and is adapted to unite the parts in a rigid manner. f v*Having thus described the invention, what I claim is A rectangular anchor or tie plate having a central opening therein and provided upon its opposite side with sets of spur-ribs arranged at right angles to each other, each set comprising outer parallel longitudinal ribs extending entirely across the plate, and inner sets of parallelribs extending from the center to the outer-,edges 0I the plate on opposite sides of the plane of the opening parallel with said outer ribs.

ln testimony whereof I aflix my signature in presence' of two witnesses. l
